DaveNWinston, I would love to see an update on your terrarium! How did it turn out?
I was thinking that a sprinkle of activated charcoal might remove any offensive odor from the fishy substrate. The 'fish dirt' substrate might be a great fertilizer for potential plantings, too!
I hope this thread picks back up . . . or, maybe I'll ponder about my 30-gallon tank-to-terrarium project here all by myself.
